WINDOW CONSTRUCTION.

Application led May 5,-y 1922.

lowing is a full, clear, and exact description y thereof, referencebeing had to the accompanying drawings, and to the letters of refer-vence marked thereon, which form apart of this specification.

This invention relates to improvements in window construction andconsists of the mat'- ters hereinafter described and more particularlypointed out in the appended claims:

One of the objects of the present inventioii is to improve theconstruction and operation of that kind of window, wherein the sash isnot only capable of a vertical sliding movement in the frame but is alsocapable of an inward swinging movement with respect thereto.

A further object of the invention is to provide novel means for lockingthe sash against a vertical Sliding movement after it has been swunginward y about the bottom end as a pivot.

The advantages of the invention will more fully appear as I proceed withmy specification.

Figure 12 is a perspective view of a sash bracket plate embodied in inimproved window construction which will be more fully referred to later.

Referring now in detail to that embodi ment of the invention illustratedin the accompanying drawings, 15 indicates as a whole, a window frameand 16 and 17 indicate the top and bottom sash associated herewith. Thewindow frame includes upright Side members 18, a top lintel 19 and asill 20, all of well known construction. Fixed to the opposed faces ofthe side` members are the inner and outer moulding strips 21 22 whichare spaced eqiiidistant apart from the parting strip 23 to provide innerand outer sashgrooves 24-25 respectively, for the bottom and top sash 17and 16. 26-26 indicate sheet metal channel strips which fit snugly inand extend the full length of the outer sash` grooves 25. Said channelstrips each include outer and inner flanges 27 28 which engage ingrooves 16* 17 inthe outer surfaces of the upright side members,

l16b and 17b of the top and bottom sash 16 and 17. (See Fig. 3.)

The Side'members 16l 17b of the sash carry threaded bushings 30 31 toreceive coacting locking pins 32-33 which may be threaded through saidbushings to engage the side members of the frame, to lock the sashagainst both a vertical sliding and an inward swinging movement as willlater appear. In the case of the pins 32 associated ,with the top Sash,the channel stiips 26 are provided with suitable holes or aperturesthrough which said pins extend to engage the Side members, as shown inFig. 3.

In the moulding strips 21 I provide short ratchet plates 21a with whichthe pins 33 co-act to hold the sash 17 in a slightly tipped or swunginward position.

Secured to the bottoni of each sash are plates 34 (see Fig. 12) each ofwhich carries a laterally projecting tongue extension 35. Each tongueextension is elliptical in cross section with its major axis arrangedvertically, and the extreme end of said tongue is bevelled off as at35u. The tongue 35 of each plate normally extends into a recess 36 in anassociated block 37 (see Fig. 11) located in each of the frame grooves24-25, there being a pair of such blocks for each' sash 16 and 17. Inthe case of the pair of blocks associated with the top sash, they arearranged, one within each channel 26. The recess 36 in each block opensthrough one edge thereof and includes a bevelled end wall or surface 38which co-acts with the bevelled end 35 of the tongue 35, as will laterappear. In each block is provided a vertically disposed opening 3i) toreceive the knotted end of a sash cord 40, the cords passing over theusual pulleys 41 in the top ends of the side frame members, to bcsecured to the associated window weights i the usual manner. (See Fig.4.)

Then the sash is in its normally upright closed position the major axisof each tongue 235 extends vertically in the associated recess :E6 sothat the blocks are free to slide in the frame grooves with the sash(see Figs. 7 and. 9) when the lower sash is swung inwardly about saidtongue as pivots, the engagement of the tongues in said recesses willnot only force said blocks against the parting strips 23 but will, onaccount of the coacting bevelled surfaces 35 and 38 force said blockslaterally outwardso that they will frictionally engage with the adjacentY parts of the frame and lock said sash against vertical movement afterit has been swung inwardly. In the case of the blocks associated withthe top sash 16, said blocks are moved to engage parts of the channelstrips 26 in a like manner. Thus no matter in what vertical positioneither sash may be in, when it is swung inwardly it is automaticallylocked against further vertical sliding movement in the frame in eitherdirection.

In addition to the automatic locking means just described, I may alsoemploy in conncctiontwith the lower sash 17, another locking means whichis brought into operation when said bottom sash is in its substantiallylowest position in the frame. Such means is as follows: To the sidemembers of the frame, just inward of the moulding, strips 21 and nearthe sill 20, I secure plates 42 each of which includes a lateral hookextension 43. Fixed to the inner face of the sash members 17 b near thebottom, are plates 44, each of which includes an inwardly projeetingbottom hoolr- 45 and an inwardly projecting top lug 46. When it isdesired toswmg the bottom sash inwardly beyond that position in which itcan be locked by the pins 33 and toothed plates 21, said pins are firstwithdrawn and the sash is then swung inwardly until the lugs 46 engagebeneath the ends of the hooks 43 on the frame plates 42. When the ysashis in this position, as shown in Fig. 5, the enoutside thereof, it ispushed outwardly to 1 disengage the hooks 43 and lugs 46 and then raiseda short distance, after which it is swung inwardly until the hooks 45engage the ends of the hooks 43 and the lugs 46 engage the top of saidhooks 43, as shown in Fig. 6. The sash is now locked in a positionconvenient for cleaning the outside of the same. To facilitate theinward and outward swinging movement of the bottom sash, I provide ahandle 47 atv the top end thereof.

By reason of the engagement of the Hanges 27-28 of the channel strips26, in the grooves 16n and 17a of the sash, said channel may shiftlaterally, in or out of its associated frame groove to accommodateitself to any contraction or expansion of the sash and thus a Weathertight connection is provided between the frame and sash at all times.

While, in describing my invention, I have referred to certain details ofmechanical construction and arrangement of parts, I do not wish to belimited thereto except as may be pointed out in the appended claims.

I claim as my invention:

1. In combination with a Window frame and a sash which is capable ofeither a vertical sliding movement or an inward swinging movement abouta horizontal axis with respect to said frame, means providing al, shdmgguldmg bearing for the sash m the frame, and coacting hook members onthe sash and frame respectively adapted for engagement with each otherwhen the Sash has been swung inwardly, to lock said sash againstvertical movement with respect to the frame.

i2. lIn combination with a window frame and a sash which is capable ofeither a vertical sliding movement or an inward swinging movement withrespect to said frame, means providing a sliding guiding bearing for thesash in the frame including a part pivoted to the sash and adapted forengagement with a fixed part of the frame, and coacting hook members onthe sash and frame respectively adapted for engagement with each otherwhen said sash has been swung inwardly, to limit the inward swing ofsaid sash and also to lock said sash against vertical movement withrespect to the frame.

3. In combination with a window frame and a sash which is capable ofeitherv a vertical sliding. movement or an inward swinging movement withrespect to said frame, means providing a sliding guiding bearing for thesash in the frame including a part pivoted to the sash and adapted forengagement with a fiiied part of the frame, and coacting hook members onthe sash and frame respectively, adapted for engagement to lock the sashagainst vertical movement in the frame when said sash has been l swunginward into one position, and to lock the sash after it has been swungfurther inward into a second position, against both a vertical slidingmovement in the frame and a further inward swinging movement.

4. In combination with a window frame having grooves in its sidemembers, and a sash which is capable of either a vertical slidingmovement or an inward swinging movement wit-h respect to said frame, ablock in each frame groove, window cords fixed to the said blocks, andplates fixed to the sash, said plates and blocks having a tongue andrecess connection, which in the inward swinging movement of the sashacts to force the blocks into frictional engagement with the walls ofthe associated groove to lock the sash against a vertical movement inthe frame.

5. In colnbination with a window'frame having grooves in the sidemembers, and a sash which is capable of either a vertical slidingAmovement or an inward swinging movement with respectto said frame, arecessed block in each sash groove window cords connected to the saidblocks, plates fixed to the sash, said plates having tongue extensionswhich project into the recesses of said blocks, said tongue extensionsacting when the sash is swung inwardly, to shift the blocks in adirection at right angles to the4 sash cords, to frictionally engage thewalls of the frame grooves and lock the sash against a vertical movementin the frame.

6. In a window construction, the combination of a Window cord blockadapted for movement in a window frame groove, said block havin a recesstherein, a tongue extension adapte to be carried by the sash,

vsaid tongue extension normally engaging in said recess, said extensionybeing of such shape that when the sash is swung inwardly into an openposition the block is shifted into engagement with the window frame tolock the sash when open against vertical movement in the frame.

7. In combination with a window frame having side members provided withinner and outersash' grooves, top and bottom window sash, slidable insaid grooves and each having a groove in the outer surface of its sidemembers, channel strips each having a flange which enters 4into arespective groove in the outer surface of the side members of bothwindow sash.

In testimony .that I claim the foregoing as my invention, I aix mysignature this 29th day of April, A. D. 1922.
